Hi Bahithyor,

Let we assume you have an executable Fortran file say name.f90 ( I assumed
Fortran 90)....Then if you are using Linux and I assumed that you have
Python,numpy and f2py installed readily...

Open your command terminal....type f2py...
You will see an usage message on Terminal with version & license detail at
the end....

then type the command as follows on terminal
(eg: My Fortran file - Hello.f90)

$ f2py -c -m tom Hello.f90

--------------------------------------
If your Fortran file is bug free then you would see  a file named 'tom.so'
which is basically a shared object file readable by python will get
generated....

For more insight I would give you an example...which I tried first.....

My Fortran code:
---------------------------------------------------------------------------

SUBROUTINE CHECK (A)
   INTEGER :: A
   PRINT*, "YOUR f2py IS WORKING FINE"
   PRINT*, "ENTERED VALUE IS =",A
END SUBROUTINE

-------------------------------------------------------------
1.) Save the above script as Hello.f90
2.) In terminal type " f2py -c -m tom Hello.f90"
3.) type ls in terminal
4.) you should see "tom.so" now
5.) type python in terminal
6.)you will get into interpreter
    >>> import tom
    >>> tom.check(2)
    YOUR f2py IS WORKING  FINE
    ENTERED VALUE IS =    2


*************** GOOD LUCK **************************

REGARDS,
HARI.
